Rapid increase of human population has triggered rapid increase in the exploitation of renewable and non-renewable resources. The way we extract natural resources is faster than what nature can replenish.
WaterIn big coastal cities, people drill wells and extract huge amount of groundwater. They use freshwater for their daily household needs. Freshwater is also pumped from coastal aquifer to supply various kinds of industries in and around the cities. Because city dwellers consume water faster than what nature can supply, the negative impact that they suffer is the intrusion of seawater. This will lead to rapid decrease in the supply of potable drinking water.
How to increase water supply
There are 4 ways that we could do to increase our supply of freshwater:
- Reuse or recycle water
- Increase storage
- Conserve water
- Find new sources

Rare Earth MaterialsCertain components inside our smart phones, modern electronic devices, and electric vehicles, are made of rare earths such as europium dysprosium,, lanthanum, neodymium, gadolinium, yttrium, terbium, and etc. Very few countries have got large rare earth deposits. China and Australia are now the main exporter of these important materials. The recent trade war between the US and China may lead to problems related to more China's restrictions on the export of these important materials to its competitors.
Overerfishing, Destruction of Coral Reef and Marine PollutionAt sea, large fishing vessels catch enormous amount of fish and other marine animals. Fishing companies that use large trawler vessels and bottom trawling nets have caused massive damages in sea floor ecosystem. The use of explosive and poisonous materials for catching fish also bring damages to our marine environment.
Forest Products and Agricultural Produce
For instance, Java, the most populated island in Indonesia. Its forests are not able to supply enough timber materials for people living in the island. Other commodities such as palm oil, rubber, cocoa beans, and coffee have to be imported too. Such products are supplied by other near by islands, i.e. Kalimantan, Sumatra, Sulawesi, Maluku, and Papua. Java is still an important producer of rice, and sugar. - written by Charles Roring
