Помогите пожалуйста перевести!
Still we tend to be poor leaders in the “hierarchy” of animal life. Despite our greatness, too often we waste; we destroy, and are too self-centered and short- sighted. Earth is so large, that even if humans destroy themselves, plus most other life forms, there will still be nature. The soil, oceans, atmosphere and weather would still interact with solar power to allow some life to exist. Earth cannot be a barren place like the moon. Humans can, then, reduce our planetary paradise into sort of a hell, but cannot, we may believe, destroy the planet itself. Even in this age of high-technology many people who live in cities and work full-time with computers see only little nature intimately. Anyway we all are still aware of the weather and the seasons. We all know that a short, rainy winter day is less pleasant than a warm sunny June day. Most of us enjoy the return of spring, and we mostly have certain pleasant or striking memories we associate with each season. The big problem is that what we like and cherish is constantly changing. Much has already changed. There is no denying that. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters, warming and cooling periods, different types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing. Global warming has become an undisputed fact about our current livelihoods; our planet is warming up and we are definitely part of the problem. However, this isn’t the only environmental problem that we should be concerned about. All across the world, people are facing a wealth of new and challenging environmental problems every day. Some of them are small and only affect a few ecosystems, but others are drastically changing the landscape of what we already know.-
