According to the projected increase in food production by 2050, water consumption would need to increase by 53% to satisfy the world population's demands for meat and agricultural production. [ 42 ] Groundwater depletion is a concern in some areas because of sustainability issues (and in some cases, land subsidence and/or saltwater intrusion ...
Deforestation is often done for several reasons, often for either agricultural purposes or for logging, which is the obtainment of timber and wood for use in construction or fuel. [7] Deforestation causes many threats to wildlife as it not only causes habitat destruction for the many animals that survive in forests, as more than 80% of the ...
Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
Natural habitats can provide Ecosystem services to humans, which are "any positive benefit that wildlife or ecosystems provide to people." [10] The natural environment is a source for a wide range of resources that can be exploited for economic profit, for example timber is harvested from forests and clean water is obtained from natural streams.
The term "conservation" itself may cover the concepts such as cultural diversity, genetic diversity, and the concept of movements environmental conservation, seedbank curation (preservation of seeds), and gene bank coordination (preservation of animals' genetic material). These are often summarized as the priority to respect diversity.
They provide various marine animals with food, protection, and shelter which keep generations of species alive. [13] Furthermore, coral reefs are an integral part of sustaining human life through serving as a food source (i.e., fish and mollusks) as well as a marine space for ecotourism which provides economic benefits.

Efforts are made to preserve the natural characteristics of Hopetoun Falls, Australia, without affecting visitors' access.. The term conservation biology and its conception as a new field originated with the convening of "The First International Conference on Research in Conservation Biology" held at the University of California, San Diego in La Jolla, California, in 1978 led by American ...
[5] [6] Further problem areas are air and water pollution (including nutrient pollution), over-exploitation, invasive species [7] and climate change. [ 4 ] Many scientists, along with the Global Assessment Report on Biodiversity and Ecosystem Services , say that the main reason for biodiversity loss is a growing human population because this ...
