What is salinization?
That is the level of salts or salt content in water or soil.
A lot of salts do we leach out or wash out of our body with sweating or with peeing.
But how do those salts come into the soil?
There are two different ways of that.
The first one is natural salinization. Where the water picks up salts from weathering rocks.
The second one is human-induced salinization, when the water, in which the salts are dissolved, is used to irrigate a crop. This crop only uses the water and, unless there is adequate drainage, the salts are left behind in the root zone.
There are as well two different classifications of soil salinity.
The first one is the saline soils. Those are the total salt levels in soil that are harmful to plant growth.
The second one is the sodic soils. Those are sodium salt levels that have a negative effect on soil and plant health.
For our personal water waste, is the ARA in Gossau responsible. It is located in the outskirt Gossau and covers the usage of ca. 15'000 people. The system started in 1971 and the last expansion was a new filter in 2012. The coordinates are 2699 058 / 1240 065.
The waters are the Greifensee, the Aabach and the Gossauerbach.

We want to put together some knowledge which we have read last week and today.
We want to make a detailed timetable as well.
Hello Together
We are doing a project about city parks and their impact on the city climate. We want to show off how important a city park is for the environment and how many people are using them frequently. It would be really interesting if we could do a collaboration with a team which also does a project on a similar topic.
For our collaboration, we thought that it would be a cool idea when we can compare the numbers and usage of city parks in different countries. So we can see what the population of different cities think about their own city parks.

What?
On which way does a city park help the city climate?
Our goal is to show off that the city parks are a necessary part of a city and aren't just for the pleasure of the people.
Possible parts in the project:
- The Location of a park
- Structure and content
- Examples of environmentally friendly parks
How?
We gonna do deeply researches on the internet and if possible some interviews with experts on this topic.
The project will be planned in the «IPERKA»-Method and will use only professional deposited sources and carefully done studies.

Resource Mining happened all around the globe and almost every time is a big concern involved, which helps the rich people to stay rich and exploit the poor people that they stay poor.
Resource Mining is more the procedure of how to get the resource out for the earth. Every resource has an individual way to mine them. More...
We know, that the oceans are covering about 65% of the world's surface. This means we are surrounded by non-drinkable water. As we know, water will be limited one day. Now the question is, how can we obtain drinkable water from the oceans.
- What are the existing processes for the desalination?
- Where are they doing this?
- Is it profitable or not?
- Is it sustainable?
