20:why should we protect the env

It is important to protect the environment because man-made disruptions to ecosystems can cause extinction and because pollution creates dangers for both animals and people.

Many of the dangers to the environment come from practices designed to make human life easier but actually threaten the long-term health and prosperity of humans.

One of the most important reasons to protect the environmentis because it helps protect different ecosystems.Over the years,humans have discovered that many ecosystems are more complex than were originally thought and are deeply connected to other ecosystems.

Human changes to one ecosystem,whether through environmental pollution or deliberate manipulation,can actually put multiples pecies in danger of extinction,necessitating the need to protect the environment.

Protecting the environment also protects humanity A great deal of pollution, especially oceanpollution, ends up affecting creatures that humans later consume,meaning that humans are ingesting toxins.

保护环境很重要，因为对生态系统的人为破坏会导致灭绝，因为污染会给动物和人类带来危险。

许多对环境的危险来自那些旨在使人类生活更容易，但实际上威胁到人类长期健康和繁荣的做法。

保护环境最重要的原因之一是因为它有助于保护不同的生态系统。多年来，人类发现许多生态系统比最初想象的更复杂，并且与其他生态系统密切相关。

人类对一个生态系统的改变，无论是通过环境污染还是故意操纵，实际上都可能将多个物种置于灭绝的危险之中，从而需要保护环境。

保护环境也保护了人类大量的污染，特别是海洋污染，最终影响到人类后来食用的生物，这意味着人类正在摄入毒素。
