The Importance of Preserving Land Area

Land area is a critical resource, providing numerous benefits beyond just being a home for life and human activity. It serves as the basis for all agricultural systems and provides essential resources such as water, air, food, fuel and medicine. Maintaining land health is crucial for future generations. Here's why preserving land area is so important:

Biodiversity

Biodiversity is the variety of different species within ecosystems and ecosystem services. A diverse range of plant and animal species contributes to stable ecosystems that can cope with change better than those with fewer species. By preserving land areas, we protect habitats that house these species, ensuring their survival and diversity. This includes forests, grasslands, wetlands, rivers, lakes, estuaries, and coral reefs - each of which supports unique assemblages of plants and animals.

Food Production

Almost three quarters of the world's population currently depend on agriculture for their livelihoods, making it one of the most important ways people earn a living worldwide. However, this reliance on agriculture has led to significant resource depletion, including the loss of productive farmland due to overuse or conversion into urban environments. By preserving land areas, particularly agricultural ones, we ensure the availability of fertile soil, allowing us to maintain our ability to produce food for the growing global population.

Climate Change Mitigation

Soil conservation and sustainable land management practices play a vital role in mitigating climate change. Soils store large amounts of carbon from the atmosphere, acting as a 'carbon sink'. However, these soils are becoming increasingly degraded, losing their capacity to sequester carbon efficiently. By sustainable land management, we aim to enhance the capacity of soils to do so, thereby reducing greenhouse gas emissions. Additionally, tree cover plays a major role in absorbing CO2 from the atmosphere. Protecting and expanding forested lands would increase carbon storage capacity, helping to slow the rate of climate change.

In conclusion, preserving land area isn't just about protecting habitat for wildlife; it's also about ensuring we have enough healthy land available for agriculture, maintaining biodiversity and preventing further climate change.
