Humans impact the environment in several ways. Common effects include decreased water quality, increased pollution and greenhouse gas emissions, depletion of natural resources and contribution to global climate change. Some of these are the direct result of human activities, whereas others are secondary effects that are part of a series of actions and reactions.
Water PollutionOne of the biggest impacts humans have on aquatic systems is excess nutrient inputs. Nutrients, like nitrogen and phosphorus, are essential to the health and survival of aquatic plants and animals. However, humans introduce large quantities of nutrients, primarily through overuse of fertilizers. Too many nutrients can rapidly reduce water quality by causing overgrowth of certain bacteria and algae that use the oxygen necessary for other species to survive. Even more problematic is that these nutrients can be transported downstream to other streams, rivers and bays. Therefore, nutrients can reduce water quality in places far removed from where they were first introduced.
Air PollutionThe majority of air pollution is the result of human activities. For example, increased fossil fuel combustion from motor vehicles, industrial factories and power plants all pump large quantities of air pollutants, such as carbon monoxide, ozone and nitrous oxides, into the atmosphere. Other air pollutants, such as lead-based compounds, can lead to serious health effects like cancer, or other types of reproductive effects and birth defects.
Climate ChangeAccording to the U.S. Environmental Protection Agency, human activities are largely responsible for an increase in temperature around the globe, primarily due to carbon dioxide and other greenhouse gas emissions. This increase in temperature is leading to changes in where crops can grow and where certain fish or animals can be found, all vital for feeding an increasing human population. The rise in global temperatures is also causing glaciers to melt, releasing water that causes sea levels to rise and threaten coastal communities and economies that rely on coastal resources.
SolutionsThere are several simple things that people can do on a daily basis to minimize their impact on the environment. For example, taking public transportation, biking or walking instead of driving will reduce carbon dioxide emissions. Reducing the amount of fertilizer applied to lawns, gardens and vegetables will lessen the likelihood of water pollution nearby, which is also beneficial for drinking water and human health. Using less energy in the home can lessen the amount of pollution put into the air by coal burning power plants. Any activity which reduces water and energy consumption can lead to positive impacts on our environment.

An environment is everything which surrounds us naturally and affects our daily lives on the earth. Everything comes under an environment, the air which we breathe every moment, the water which we use for our daily routine, plants, animals and other living things, etc around us. An environment is called healthy environment when the natural cycle goes side by side without any disturbance. Any type of disturbance in the nature’s balance affects the environment totally which ruins the human lives.
Now, in the era of advance living standard of the human being, our environment is getting affected to a great extent by the means of air pollution, noise pollution, deforestation, water pollution, soil pollution, acid rain and other dangerous disasters created by the human beings through technological advancement. Therefore, we all must take an oath together to protect our natural environment to keep it safe as usual forever.

Wind energy has the advantage of protecting the environment, avoiding the release of toxic gas, which is also the energy for the movement of hot air balloons, sailing boats and many other vehicles. In addition, wind energy is also used to generate electricity, but that is also a big disadvantage because the wind blows infrequently and the uneven speed causes low productivity. But anyway, it is also a method, an energy source to protect the environment. mong là bạn dùng được vì mình viết hơi sơ sài :)))

In the world there are many types of energy sources, wind energy is one of them. It is a renewable energy source, so it has many advantages. Firstly, it is not harmful to the environment, people will not need to worry about environmental problems when using it. Second, wind energy lasts forever, and like tidal or solar energy, we will never run out of it. Third, it is cost effective. There are no costs associated with buying or transporting fuel into wind turbines, like coal-fired power plants. In addition, with advancements in technology, wind energy will become cheaper, thereby reducing the amount of capital that countries have to spend to meet their energy needs. However, it also has disadvantages. Windmills will make noise for everyone nearby, causing noise pollution. Not only that, the animals around it can also be in danger. Are birds safe to crash into windmill wings? Despite the downsides, the advantages of wind power are also great. It would be great if we humans use it in the future.

Among numerous popular leisure activities, I am completely absorbed in doing sports because of three reasons below. First of all, playing sports helps to keep our shape, so you can have a well-trained body that makes you feel more self-confident with an impressive appearance. Secondly, it is believed that taking part in a lot of sports can improve the quality of your life. Indeed, not only does practising sports help to avoid a number of health problems such as heart attack or high blood pressure but it also reduce our stress. This explains why people regard it as an ideal means of relaxation at the end of the hard-working day. Thirdly, this activity is known as a way to develop various social skills. When you join a game or practise with your teammates, you will learn how to interact with other people as well as promote your teamwork spirit and game strategies. In conclusion, I really have a great interest in playing sports and I strongly believe that it is a cure for both our physical and mental problems.

My favourite after school activity is playing badminton. There are some reasons why I like it. First, I can improve my health by playing it. It makes me feel energetic everyday. Furthermore, I enjoy the feeling of the badminton flying in the air. During the game, I can change the direction of badminton with little effort and beat my opponents. Besides that, I can make many friends when I play badminton. I often play it with various types of people. We can improve our skills through discussion and practice. Also, we can talk about many interesting things when we have a break. Finally, playing badminton is not as intense as other sports such as basketball or soccer. It lessens the possibility of being hurt. To sum up, playing badminton benefits a person not only physically but mentally as well. I usually play at least once or twice a week.

My favourite leisure activity is reading. I like reading because it is a hobby that is useful and interesting: useful because you can find a lot of knowledge of all areas that you need; interesting because the books can give you the joy and help you relax after a day of toil etc... Especially, when you join the forum, you can meet a lot of people who have interests similar to yours, comment on the books or novels that interest you.
I love books and also natural as reading books. At the age of ten, I was awarded "The Scarlet Sails" of Alexandre Green by my grandfather. It is the first of book that I have been. I read it does not know how many times (Up to now, I still love it and occasionally read it again). My love for books begun.
I usually spend almost of free time in choosing the book with my friends, participate in dicussion on the forum and reading (of course!). Every weekend and all holidays when I have no work to do, I often read books and ruminate on it. I also help some friends can select the genres of books that they like.
I always hope that I will have my own library in my future. I love books very much and perhaps, I couldn't live without them.

There are a lot of activities that you can do in your leisure time. Some people are so tired of work that they prefer to use their free time just for resting and sleeping. Others spend their free time on their favourite activities. For example, they listen to music, play their favourite musical instrument, go on a picnic, take a trip, go to the nature and enjoy the fresh air, hang out with their friends, go partying, go shopping, visit their relatives, spend some time with their kids and play games with them, read and write, watch TV, watch movies or cartoons, go to the theatre, surf the net, cook, do some gardening, etc. Some people like me choose sports to enjoy their free time. Among different kinds of sports, I prefer basketball.
When you play basketball with your team mates you have a chance to get rid of all the negative energies that are piled up in you throughout work or study time. Your body is wholly involved. Basketball involves both your mind and your body. It’s an extremely physical activity, so that even your finger tips have to be strong. In basketball you need both stamina and speed to be a successful player. It’s not that important if you’re not tall. Your strength is of much more importance. Both feet and hands must be strong. Even you need to be wise in this game. If you know where to stand so that your rival has a weak chance of blocking you, you’ll more successfully get close to the basket to shoot and score. Sometimes, by being wise and finding the right place to stand and block the rival saves your team.
Basketball is a team work and this is what I like the most about this sport. You learn how to cooperate with other team mates. Sometimes, you need to sacrifice yourself by blocking the rival so that your team mate can find space to go to the basket and score. Passing the ball to other members of your team makes the chance of winning higher and higher.
All in all, basketball is so enjoyable and fun if you play it in a group, not individually.
