Should we be rewilding more land?

Every day in the US, 6,000 acres of open land are cleared for various purposes such as farming, housing, roads, and others. This has led to concerns among scientists 【小题1】 believe that losing more open land can harm the planet. Natural habitats such as untouched forests, grasslands, and waterways provide numerous benefits 【小题2】 wildlife habitats, clean water, and reduced air pollution. To counter this trend, efforts are underway 【小题3】 the world to return animals and plants to certain areas. However, some people argue that rewilding is 【小题4】 expensive and risky process that may not work and could cause harm.

Despite the potential risks, rewilding can help slow down climate change by restoring forests that absorb harmful gases like carbon dioxide. It can also prevent species from 【小题5】(die) out and reset natural ecosystems. For example, gray wolves 【小题6】(reintroduce) in Yellowstone National Park in 1995, after being hunted to extinction there. The wolves reduced the booming population of elks (麋鹿), 【小题7】 gave the plants the elks ate a chance to thrive and serve as habitat for animals like beavers and birds.

【小题8】 its environmental benefits, rewilding can also provide jobs for workers and scientists and attract visitors to an area. Despite the potential concerns and risks 【小题9】(associate) with rewilding, it is an important tool for protecting the planet and its diverse ecosystems. As such, efforts 【小题10】 be made to ensure that rewilding projects are conducted responsibly and with careful consideration of their potential impact on the environment.

Earth Day is a yearly event celebrated on April 22. Various activities【小题1】( hold ) worldwide to show support for environmental protection. Here is a brief history of【小题2】event.

In the 1960s, Americans were becoming aware of the effects of pollution【小题3】the environment.

China has announced the formal establishment of its first ten national parks. Giant Panda National Park (GPNP) is one on the list. GPNP is located in Central China 【小题1】(spread) across Sichuan, Shanxi and Gansu provinces. Once 【小题2】(complete), the new national park will include 67 existing panda reserves.

Connecting these reserves and establishing protected areas between the different areas will allow pandas to travel between the areas and 【小题7】(hope) crossbreed (杂交) and strengthen the panda population. This is a focused effort to help the animals to reproduce.

The combination of these panda reserves is an enthusiastic commitment by the Chinese government to protect these 【小题8】(except) animals. The good news is that there is evidence 【小题9】 the population appears to be growing. The International Union for Conservation of Nature has upgraded the species from endangered to threatened. 【小题10】 this positive improvement, there is still a lot the world needs to do to help secure the survival of this precious species.
