Our role is to conserve the earth's resources and the ecosystem, and {BLANK}.
|
practice sustainable development
|
|
|
Soil is just one of the valuable resources that people should use wisely. The wise use and preservation of resources is called {BLANK}.
|
conservation
|
|
|
As we conserve natural resources, we also conserve the {BLANK} in the ecosystem.
|
balance of life
|
|
|
This means utilizing the earth's resources to meet the needs of the present generation, without compromising the needs of the future generation.
|
Sustainable development
|
|
|
What are the strategies for maintaining the balance of life in the ecosystem?
|
1. Conserving the needs of living things (soil conservation and water conservation)
2. Protecting forest and wildlife ecosystem (wildlife conservation and habitat restoration) |
|
|
Conservation of resources must be praticed for {BLANK}.
|
living things to survive
|
|
|
Name the ways that we can conserve Earth's resources.
|
reducing water and air pollution, practicing proper waste disposal, and burying of biodegradable materials
|
|
|
{BLANK} exposes the topsoil, which affects the nutrient content of the soil. As the topsoil disappears, plants' growth is affected. That's why soil must be conserved.
|
Soil erosion
|
|
|
Soil is protected from erosion when:
|
1. The soil surface is covered by living plants. The fibrous roots of plants hold the soil.
2. Soil contains plenty of organic matter called households (coming from dead plants and animals) to glue particles together. 3. Soil has the right amount of particles - clay, sand, silt pebbles, and gravel. |
|
|
{BLANK} helps restore the nutrients of the soil. This will make the pants and other organisms live and grow.
|
Soil conservation
|
|
|
This involves employing agricultural soil management methods. Some of the most effective methods include strip cropping, which alternates strips of crop and uncultivated land to minimize erosion and water runoff, and contour farming, which is the planting of crops along the contours of sloping lands to minimize erosion and runoff. Terracing also reduces erosion and runoff on slopes.
|
Soil conservation
|
|
|
Growing {BLANK} restores essential nitrogen in the soil.
|
legumes, such as string beans or soybeans
|
|
|
{BLANK} resources are essential for drinking, bathing, cooking, irrigation, industrial processes, and plant and animal survival.
|
Clean freshwater
|
|
|
The global supply of freshwater is distributed unevenly. Most sources of freshwater supply - ground water reservoirs and rivers - are noe polluted, so {BLANK} is essential.
|
water conservation
|
|
|
What happens when trees are cut down?
|
forest animals lose their homes
|
|
|
{BLANK} means keeping a record of the number and variety of different organisms and ecosystems in a certain area.
|
Wildlife conservation, preservation, and management
|
|
|
{BLANK} is essential as ecosystems respond flexibly to damage or change. This way, we can protect living things in this ecosystem.
|
Preserving biodiversity
|
|
|
State some ways of protecting and conserving wildlife.
|
1. Protect a sanctuary - and area declared protected by the government like the Calauit Game Reserve and Sanctuary in Palawan
2. Support projects of the government in protecting the wildlife ecosystem 3. Do not patronize products made from the body parts of animals, such as furs and horns. 4. Join organizations that conduct educational campaigns and give information on how to protect and conserve the wildlife ecosystem. 5. Help raise funds to support projects for wildlife conservation. |
|
|
State some government projects that are protecting the wildlife ecosystem.
|
1. The Pawikan Conservation Project (Baguan Island Marine Sanctuary) /n 2. The Philippine Tarsier Conservation Project (Bohol)
3. The Philippine Eagle Conservation Project (Makiling Botanic Gardens) 4. The Tamaraw Conservation Project (San Jose, Occidental Mindoro) |
|
|
{BLANK} will help restore the forest ecosystem and the wildlife in it.
|
