Humans, like all other creatures, have apparently changed their environment, but their changes are generally more dramatic than those of other species. Some of these changes, such as the destruction of the world's rainforests, the provision of pasture for livestock, or the drying up of almost three-quarters of the Aral Sea, were once the world's fourth largest freshwater lake for irrigation, leading to changes in climate patterns, which in turn changed flora and fauna Species distribution, scientists are trying to understand the long-term impact of human activities on ecosystems, while environmentalists are dedicated to experts in various fields. Citizens of the United States and other countries are trying to reduce the impact of human activities on population growth in the natural world.
Human population growth may be regarded as the root cause of almost all world environmental problems, with more and more people each year Joining the world, with the increase of population, more pollution will be produced, more habitats will be destroyed, and more natural resources will be consumed. Even if new technological progress can halve the environmental impact on everyone, once the world population is doubled, the earth will not be better than before.
A person's life is a process of growth. In fact, standing here is a process of growth. If a person's life must be composed of various choices, then I will grow up with these choices.
Once I hoped to go to university in the future, but that has passed. You know, I came here, and now I am thinking about what will happen in the future.
We all know that to live a low-carbon life, our environment is getting worse and worse, and low-carbon life is more and more popular. Low carbon life is of great use to us. It helps to save energy and reduce pollution.
It can reduce the amount of carbon dioxide, the main cause of the greenhouse effect, and help to reduce the greenhouse effect and keep the environment beautiful and clean. Therefore, we should first live a low carbon life. When we go out, we should take a bus or bike instead of driving a car.
Cars not only emit carbon dioxide, but also waste energy. We'd better not use plastic bags that will bring white pollution. We should use environmental protection bags.
Planting trees is of great use. Trees can absorb carbon dioxide and release oxygen. Finally, we should start with small things.
Therefore, as students, we should turn off the lights when we leave, turn off the tap in time, reuse our textbooks, etc.
