Should we set aside half of planet Earth as a nature preserve?

According to the Half-Earth Project, which is associated with the E.O. Wilson Biodiversity Foundation, devoting half of the global surface to nature would protect 85% of today's species from extinction.

How much land should we protect for other species?

Delegates at the 1992 Fourth World Congress on National Parks and Protected Areas, a decennial international conference that serves as a global forum for setting the agenda for protected areas worldwide, recommended that “protected areas cover at least 10 percent of each biome by the year 2000.”

Are nature reserves effective?

Many nature reserves are established to protect the habitat needs of particular endangered species of interest but their effectiveness for protecting other species is questionable. ... In addition, four species exhibited a low proportion of highly suitable habitat inside the core zones of nature reserves.

Are protected areas protected forever?

Protected area coverage worldwide has grown since 2016 — now covering 14.9 percent of land and 7.3 percent of oceans — but a new analysis reveals gaps in the protected area system, highlighting essential places for biodiversity and ecosystems that need further protection. ...

What happens if we dont conserve wildlife?

The natural habitats of animals and plants are being destroyed for land development and farming by humans. ... The extinction of wildlife species will certainly have a fatal impact on human race as well.

What is the Half-Earth idea?

Half-Earth is a call to protect half the land and sea in order to manage sufficient habitat to reverse the species extinction crisis and ensure the long-term health of our planet. The Half-Earth Project is bringing this goal to life.

Why should land be protected?

Conserving environmental resources

Protecting land offers numerous environmental benefits. Conserving land and open space can provide habitat for native plants and animals, and enhance ecosystem services.

Why is it important to protect the land by preserving large areas?

Scientists have suggested that ambitious land-protection efforts could help limit the chances of such outbreaks worldwide (as development pushes deeper into formerly “wild” areas, people are exposed to more new disease vectors; preserving intact habitat undamaged by human development would reduce those instances).

Why should we protect the earth?

Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilisation and sustain our economies.

Why are nature reserves so important?

Droughts bring with them the increased risk of fire as vast areas that usually experience rains are left dry, which in turn restarts the whole cycle. Healthy nature reserves and national parks mean cleaner water for our taps, so be sure to support your local spot with a long-weekend getaway.

What are the advantages of nature reserves?

Strictly regulated nature reserves provide highly valuable ecosystem services. Strict protection provides benefits in terms of carbon stores and recreation. National and global benefits outweighed costs to local livelihoods. This state could be replicated by managing the same area with alternative approaches.

Are nature reserves protected?

From meadows and reedbeds to woodlands and beaches, nature reserves are protected places where wildlife can live and ultimately thrive.

How effective is protected areas?

Protected areas (PAs) are a key strategy for conserving nature and halting the loss of biodiversity. Our results show that while many PAs are effective, the large focus on increasing terrestrial coverage toward 17% of the earth surface has led to many PAs failing to stem human pressure.

Why are protected areas effective?

Protected areas help to mitigate extreme weather events, enhance carbon storage, and provide space for plants and animals to adapt to a changing climate. 4. To maintain functioning ecosystems and the benefits they provide. Protected areas provide clean air and water, healthy soils, wild foods and medicines.

How management of protected areas are done?

Protected area practitioners undertake many other tasks such as species management, anti-poaching patrolling, providing for visitor services, dealing with emergencies, research and monitoring, and restoration work. At the government policy level, responses to development threats to protected areas need to be made.
