Important strategy in attempting to reduce deforestation
Reforestation
Companies are allowed only to cut down old trees or a particular species
Put laws in place to ensure that people do not damage these protected areas ,such as illegally cutting down trees
Best known for being valuable sources of wood for buliding and carpentry . Wood from mangrove trees are used to make houses
Bananas and mangoes, vegetables like cucumbers and egg plants
Trekking, camping and birdwatching
Depend on their physical environment to meet their basic needs ,such as food, water , shelter and clothing
Earth´s atmosphere is behaving similar way to a green house .
Green house gases consists of carbon dioxide , nitrous dioxide and methane , these gases are capable of trapping heat
They keep the Earth´s average temperature warm at 15 degrees celscius
Carbon dioxide is one of the most important greenhouse gases found naturally in the Earth ' s atmosphere
Deforestation is responsible for approximately 20% of the total amount of carbon dioxide added to the atmosphere as a result of human activities
The permanent removal of tropical rainforests is known as deforestation
The dense roots of mangroves plants help to trap and stabilise loose sediments on the coast
Sediments are less likely to be washed away by waves , currents and tides
The roots ,trunks and branches of mangrove plants causes friction with waves hitting the coast
The waves loses a significant amount of energy , thus reducing coastal erosion
The leaves , branches and stems of rainforest plants slow down falling raindrops before they reach the ground
More water can infiltrate and percolate into the soil , thus reducing surface runoff
Raindrops hit the soil with less force
The roots of rainforest plants also bind the soil together , making its hard to erode .
The soil erosion is minimised
Tropical rainforests are rich in biodiversity . Their warm climate and the abundance of water and food sources all around
They absorb carbon dioxide from the atmosphere during photosynthesis.
The absorbed carbon dioxide is been absorbed in solid form in the plants - in their leaves, branches, stems and roots . Dead leaves and branches that fall to the ground add carbon to the soil .
They generate oxygen through photosynthesis
Photosynthesis is the process in which they absorb carbon dioxide , water and sunlight to produce food for their own survival and growth . Further more, they are capable of producing oxygen throughout the year as they are evergreen
