The causes of deforestation

Tropical forest trees, like all green plants, take in carbon dioxide and release oxygen during photosynthesis. When trees are cut down and burned or allowed to rot, their stored carbon is released into the air as carbon dioxide. And this is how deforestation and forest degradation contribute to global warming.

We are cutting down rainforests for many reasons, including:

• wood for both timber and making fires;
• agriculture for both small and large farms;
• land for poor farmers who don’t have anywhere else to live;
• grazing land for cattle;
• pulp for making paper;
• road construction; and.
• extraction of minerals and energy.

• Natural causes as hurricanes, fires, parasites and floods.
• Human activities as agricultural expansion, cattle breeding, timber extraction, mining, oil extraction, dam construction and infrastructure development.

The most common pressures causing deforestation and severe forest degradation are agriculture, unsustainable forest management, mining, infrastructure projects and increased fire incidence and intensity.

A Well-curated List of the Top 10 Most Dangerous Forest in the World:

• Gadchiroli Forest (India)
• Amazon Rainforest (South America)
• Aokigahara Forest (Japan)
• Hoia – Baciu Forest (Romania)
• Dering Woods (England)
• Sambisa Forest (Nigeria)
• Daintree Rainforest (Australia)
• Darien Gap (Central America)

At just over a meager 110,000 square miles, the forests of New Guinea are the third-largest tropical forest in the world (after the Amazon and Congo basin).

Here are 10 examples of plants that produce the most oxygen:

• Snake Plant (Sansevieria trifasciata zeylanica)
• Spider plant (Chlorophytum comosum)
• Weeping fig (Ficus benjamina)
• Gerbera Daisy (Gerebra Jamesonii or viridfolia)
• Peace lily (Spathiphyllum wallisii)
• Aloe vera (Aloe barbadensis miller)
• Orchids (Orchidaceae)

Algae, when used in conjunction with AI-powered bioreactors, is up to 400 times more efficient than a tree at removing CO2 from the atmosphere. Trees “consume” it as part of their photosynthesis process by “absorbing” carbon into their trunks and roots and releasing oxygen back into the air.

If the concentration of algae increases in the water body, then it causes depletion of oxygen in the water. This algal bloom covers the water surface, secrete toxins and reduce oxygen content of water. Oxygen deficiency may cause the death of aquatic animals.

Dissolved oxygen is necessary to many forms of life including fish, invertebrates, bacteria and plants. Bottom feeders, crabs, oysters and worms need minimal amounts of oxygen (1-6 mg/L), while shallow water fish need higher levels (4-15 mg/L)⁵. Microbes such as bacteria and fungi also require dissolved oxygen.

Like most plants, many algae produce oxygen during the daylight as a by-product of photosynthesis. At night these algae consume oxygen, but usually much less than was produced during the daylight.

As you know, algae produce the highest levels of oxygen in the planet and can capture carbon dioxide. so we can use this ability to reduce carbon dioxide and produce more oxygen.

This is usually a major source of oxygen in fish ponds. Algae blooms in natural water bodies or fish ponds normally produce much more oxygen in the daylight than they consume during the night, but some situations reduce the amount of oxygen a bloom produces without reducing its nighttime oxygen consumption.

By various estimates, the total percentage of oxygen that’s produced from these tiny, modest single-celled critters ranges from 50 to 85 percent! And there’s one breakout star, a single-celled algal organism called Prochlorococcus, which produces roughly 20% of the world’s oxygen just on its own.
