- Bio Food
The best way you can do this is in an aquaponics system which has a very high efficiency rate because you can grow plants vertically, so in a small space you can have a very high density compared to growing horizontally and if you combine that with the implementation of various renewable energy sources you basically only have to buy fish feed, the profit rates can be huge!
And wait, what is aquaponics?
Aquaponics combine the aquaculture which is the growing of fish in a tank or in a small pond & hydroponics which is the process of growing plants without soil.
In this system the fish’s waste is the nutrient for the plants and the rate of growth for plants is double vs the traditional way to harvest vegetables.
2. Renewable energy
This is one of the most hot topics right now because everyone needs more and more electricity to function: to charge electric cars, or to heat their homes.
You can try one of the following:
- Solar panels
- Wind turbine
- Or you can even invest in a system that captures wave energy and converts it into electricity
3. Recycling
With population growth the amount of waste that is all around us has increased enormously, so a solution to this problem would be much sought after, you can choose to clean up the rivers, or make a smart sorting system, or a landfill where the waste is the raw material for electricity generation.
Opportunities are everywhere, you just have to see them!
