Lingkungan Hidup tempat kita tinggal dan hidup ternyata sangat rapuh. Tidak mudah untuk menjaganya bahkan ancaman kerusakan akan bertambah tinggi di era dunia yang semakin tua ini. Sebelumnya mari kita kenali apa saja penyebab kerusakan lingkungan hidup ini.
Environment where we live and life was very fragile. Not easy to keep even the threat of damage will increase at the time when the world is getting older. Previously let’s find what are the causes of this environmental damage.
- Hujan abu vulkanik, menyebabkan gangguan pernafasan.
- Lava panas, merusak, dan mematikan apa pun yang dilalui.
- Awan panas, dapat mematikan makhluk hidup yang dilalui.
- Gas yang mengandung racun.
- Material padat (batuan, kerikil, pasir), dapat menimpa perumahan, dan lain-lain.
Based on causes to the damage, forms of environmental damage divided into 2 types, such as:
1 Environmental Damage Due to Natural Events
Various forms of natural disasters lately struck Indonesia has resulted in environmental damage. Enormity of the tsunami that devastated the earth Veranda of Mecca and Nias, as well as 5 Richter scale earthquake that leveled the DIY and the surrounding region, is an example of a natural phenomenon in a flash capable of changing the face of earth .Other natural Events that have an impact on environmental degradation, among others:
a. Volcanic eruptions
Volcanic eruptions occur due to activity of magma in the earth’s crust which cause strong pressure out through the top of the active mountain. Dangers caused by volcanic eruptions such as:
- Volcanic ash, causing respiratory problems.
- Lava hot, destructive, and deadly anything that passed.
- Hot clouds, can turn off the living creatures that passed.
- Toxic gas.
- Solid material (rock, gravel, sand), can override housing, and others.
b. Gempa Bumi
- Berbagai bangunan roboh.
- Tanah di permukaan bumi merekah, jalan menjadi putus.
- Tanah longsor akibat guncangan.
- Terjadi banjir, akibat rusaknya tanggul.
- Gempa yang terjadi di dasar laut dapat menyebabkan tsunami (gelombang pasang)
An earthquake is the vibration of the earth’s crust that caused by several things, including activities of magma (volcanic activity), the ground down, as well as movement of the plates on the ocean floor. Humans can measure how intense of an earthquake, but the man simply can not predict when an earthquake will take place.
Therefore, the danger posed by an earthquake more powerful than the volcanic eruption. At the time of the earthquake happened, several events occurred as a result of direct or indirect impact, including:
- Various buildings collapsed.
- Broke ground on the earth’s surface, the road broken.
- Landslides caused by shocks.
- Floods, due to damage to the embankment.
- An earthquake on the ocean floor can cause a tsunami (tidal wave)
C. Angin Topan
- Merobohkan bangunan.
- Rusaknya areal pertanian dan perkebunan.
- Membahayakan penerbangan.
- Menimbulkan ombak besar yang dapat menenggelamkan kapal
Hurricanes occur due to air flow from areas of high pressure toward to areas of low pressure.
This differences of air pressure occurs because of the air temperature differences are striking. The attacks of hurricanes for countries in the Pacific Ocean and the Atlantic region is a common thing. For regional areas in California, Texas, ranged until in Asia such as Korea and Taiwan, the danger of a catastrophic hurricane happened seasonally. But in Indonesia began to feel in mid-2007 and It is showing that climate change has occurred in Indonesia, which was caused by the phenomenon of global warming.
Dangers of hurricanes can be predicted through the satellite photos that illustrate the state of the Earth’s atmosphere, including formation of hurricanes picture, direction, and speed. Attacks hurricane (tornado) can cause damage to the environment in the form of:
- Tear down the building.
- Damage to agricultural land and plantations.
- Endanger the flight.
- Cause large waves that can sink the ship
2. Kerusakan Lingkungan Hidup karena Manusia
- Terjadinya pencemaran (pencemaran udara, air, tanah, dan suara) sebagai dampak adanya kawasan industri.
- Terjadinya banjir, sebagai dampak buruknya drainase atau sistem pembuangan air dan kesalahan dalam menjaga daerah aliran sungai dan dampak pengrusakan hutan.
- Penebangan hutan secara liar (penggundulan hutan).
- Perburuan liar.
- Merusak hutan bakau.
- Penimbunan rawa-rawa untuk pemukiman.
- Pembuangan sampah di sembarang tempat.
- Bangunan liar di daerah aliran sungai (DAS).
- Pemanfaatan sumber daya alam secara berlebihan di luar batas.
2 Environmental Damage due to human
Man as ruler of the earth’s environment plays a major role in determining the environmental sustainability. Human beings as God’s creatures who stay at the top of food chain is able to change the face of the world starting from the simple pattern to modern life as it is today.
But unfortunately, what people do is often did not matched to the next generation impact. A lot of success achieved by humans have an adverse impact on environmental sustainability.
Some forms of environmental degradation due to human factors, among others:
- Pollution (pollution of air, water, soil, and noise) as the impact of the industrial area.
- Flooding, as a result of poor drainage or sewerage system and failure to keep up watersheds and the impact of forest destruction.
- Landslides, as a direct result of human activity on forest.
Beberapa damage that may directly or indirectly have an impact on environmental degradation, among others:
- Illegal logging (deforestation).
- Damaging mangroves.
- Hoarding swamps for settlement.
- Disposal of waste in any place.
- Illegal buildings in the watershed (DAS).
- Utilization of natural resources excessively out-of-bounds.
Apakah penyebab kerusakan lingkungan hidup pada poin no. 1 disebabkan oleh poin no.2 ?, mari kita jaga lingkungan hidup ini. Karena ada kesatria-kesatria seperti malaikat-malaikat kecil bersayap yang ternyata cukup indah dan hampir kita lupakan dan tidak pernah peduli terhadap mereka dan mereka memerlukan rumah untuk tempat tinggal.
Whether the cause of environmental degradation stated in point no. 1 caused by point no.2?, Let’s keep this environment balance. Because little knights like little winged angels who is beautiful and almost forgotten and never care about them and they need a house for shelter.
