The agriculture and forestry sector plays a crucial role in providing food, settlements, and raw materials such as timber for human society. However, uncontrolled activities create severe socio-scientific issues. Green Technology applications provide sustainable practices to conserve forest resources and protect agricultural productivity.
Human agricultural and logging activities create environmental impacts that Green Technology can help to overcome.
Population growth and lifestyle changes have increased the demand for housing, food, and transport, prompting massive forest clearing and intensive farming. Unregulated logging leads to landslides, floods, loss of biodiversity, and disruption to the carbon dioxide-oxygen cycle.
In agriculture, open burning triggers regional haze, while chemical fertilisers and pesticides cause soil acidification and river pollution.
To counter these issues, Green Technology introduces sustainable practices such as converting farm waste into organic compost, replanting trees, gazetting protected forest reserves, strictly regulating logging activities, and deploying forest rangers to enforce forestry laws.
Forests are cleared for new settlements or agriculture. When not controlled and regulated properly, this leads to landslides, floods and mud floods, and extinction of flora and fauna.
Massive forest exploration interferes with the gas cycle of Earth because forests act as the 'lungs of Earth'. The conversion of carbon dioxide into oxygen is only done by plants through photosynthesis.
Farmers who practise open burning on their farms cause severe haze that compromises air quality domestically and across neighbouring countries.
Widespread use of pesticides and chemical fertilisers leads to soil pollution, increasing soil acidity and rendering soil unsuitable for agriculture. Runoff of absorbed chemical substances into nearby rivers contaminates aquatic water bodies.
Treating and processing agricultural waste into compost is a Green Technology practice that controls the balance of nature.
Replanting trees helps to maintain and preserve existing flora and fauna species.
Regulating logging activities helps to conserve forest resources.
Gazetting more forest reserves helps to maintain a balanced forest ecosystem.
A forest ranger guards and coordinates forest development projects, enforces factory-operation laws, prevents trespassing in recreational forests, checks and monitors forest operation licensing for timber-based industries, and enforces forestry law by taking legal actions when necessary.

What causes landslides and mud floods to happen in the forestry sector?
State the effect of using excessive chemical fertilisers in agriculture.
State two measures that can be taken to reduce deforestation.
Deforestation only impacts local plants and wild animals.
Deforestation disrupts global gas cycles by reducing photosynthesis (which converts carbon dioxide into oxygen) and causes broader catchment disasters such as mud floods, landslides, and river pollution.
Composting is just an ordinary waste dumping method.
Composting is an active Green Technology practice that treats and processes agricultural waste into natural nutrients, controlling the balance of nature without reliance on polluting chemical fertilisers.
1 Which of the following is a direct consequence of open burning carried out on agricultural farms?
2 How does massive forest exploration interfere with Earth's gas cycle?
3 Treating and processing agricultural waste into is a Green Technology practice capable of controlling the balance of nature.
4 The widespread use of pesticides and chemical fertilisers increases the of agricultural soil, making it unsuitable for crops.
