Explanation:
Rabbits impact our national parks and reserves by: reducing the regeneration of native plants, through grazing and ringbarking of saplings. Attracting and providing food for other pest animals, such as wild dogs, foxes and feral cats, which can then prey on native animals.
18. The soil sustains most living organisms, being the ultimate source of their mineral nutrients. Good management of soils ensures that mineral elements do not become deficient or toxic to plants, and that appropriate mineral elements enter the food chain.
19. One Black Bear plant prevents more CO2 emissions than one million trees can sequester. here are 250 trees per hectare in a 70-year-old forest, which means that one Black Bear plant prevents CO2 emissions equal to that stored per year in a 4000-ha forest.
20. The soil sustains most living organisms, being the ultimate source of their mineral nutrients. Good management of soils ensures that mineral elements do not become deficient or toxic to plants, and that appropriate mineral elements enter the food chain. Soil management is important, both directly and indirectly, to crop productivity, environmental sustainability, and human health. Because of the projected increase in world population and the consequent necessity for the intensification of food production, the management of soils will become increasingly important in the coming years. To achieve future food security, the management of soils in a sustainable manner will be the challenge, through proper nutrient management and appropriate soil conservation practices. Research will be required to avoid further degradation of soils, through erosion or contamination, and to produce sufficient safe and nutritious food for healthy diets.
21. Caribou are an important resource for indigenous peoples, a prey species for carnivores and omnivores, such as bears and wolves, and a critical source of nutrients for the soil in areas where they forage in large numbers. ... They are also the only deer species where males and females both have antlers.
22. Because lichens enable algae to live all over the world in many different climates, they also provide a means to convert carbon dioxide in the atmosphere through photosynthesis into oxygen, which we all need to survive. ... Lichens can provide us with valuable information about the environment around us.
23. Well adapted to its environment, the Arctic fox is shielded from sub-zero winter temperatures by its thick, white fur coat. ... Foxes seek shelter in snow burrows during unusually cold weather, and can lower their metabolic rate during cold snaps and food shortages to retain
24. Harnessing power from the wind is one of the cleanest and most sustainable ways to generate electricity as it produces no toxic pollution or global warming emissions. Wind is also abundant, inexhaustible, and affordable, which makes it a viable and large-scale alternative to fossil fuels.
