While many plants have been used for food, a small number of staple crops including wheat, rice, and maize provide most of the food in the world today. In turn, animals provide much of the meat eaten by the human population, whether farmed or hunted, and until the arrival of mechanised transport, terrestrial mammals provided a large part of the ...
Ecosystem services are the various benefits that humans derive from healthy ecosystems. These ecosystems, when functioning well, offer such things as provision of food, natural pollination of crops, clean air and water, decomposition of wastes, or flood control. Ecosystem services are grouped into four broad categories of services.
These trees have been modified to improve photosynthetic efficiency, enabling them to capture more carbon dioxide (CO₂) and produce greater woody biomass than conventional trees. Living Carbon’s mission is to leverage technology to combat climate change while promoting biodiversity and restoring degraded ecosystems.
Trees growing in arid and/or cold environments do so especially slowly. Thus, tree trunks and branches can remain on the forest floor for long periods, affecting such things as wildlife habitat, fire behaviour, and tree regeneration processes. Some trees leave behind eerie skeletons after death.
Forest provides timber for humans, food, water and shelter for the flora and fauna tribes and animals. The nutrient cycle between organisms forms food chains and fosters a biodiversity of species. The Carson Fall in Mount Kinabalu, Malaysia is an example of undisturbed natural resources. Waterfalls provide spring water for humans, animals and ...
Green plants provide a substantial proportion of the world's molecular oxygen; the sugars they create supply the energy for most of Earth's ecosystems, and other organisms, including animals, either eat plants directly or rely on organisms which do so. Grain, fruit, and vegetables are basic human foods and have been domesticated for
Human composting is emerging as an end-of-life alternative that is friendlier to the climate and the Earth — it is far less carbon-intensive than cremation and doesn’t use chemicals involved ...
Soil organisms exhibit a wide array of feeding preferences, life-cycles and survival strategies and they interact within complex food webs. [30] Consequently, species richness per se has very little influence on soil processes and functional dissimilarity can have stronger impacts on ecosystem functioning. [31]
