Hip Hop Science Spaza collaborated with learners from Cedar High School of the Arts and researchers from Stellenbosch University’s Division of Molecular Biology and Human Genetics (MBHG) to host another successful intervention! This time, learners from Cedar High interacted with MBHG researchers to learn all about Tuberculosis (TB). Researchers set up awesome learning stations for the learners where they could participate in fun activities and examine scientific equipmentThe learners then wrote and recorded their OWN songs which they performed for their peers and parents at the final event. Pretty cool, eh!   

Hip Hop Science Spaza created an opportunity for young people to interact with researchers to explore what TB is, how it is spread, the signs and symptoms of TB, how TB is diagnosed, how TB is treated and stigmas surrounding TB. Learners arrived for the sessions shy and nervous but best believe that by the end of the week, they were fired up to be a part of the TB conversation!

Start a home garden

You can plant your own fruit and veggies in a home garden. You will be helping the environment and saving money at the same time!

Make your own compost

Put leftover food in a compost heap. You can use compost to grow new plants. Making compost also reduces space used for landfills and creates healthy soil.

Plant indigenous

Plant indigenous species of plants. They use less water and provide food and habitat for animals.

Don’t use plastic

Plastic bags harm animals and the environment and take years to break down. Use your own canvas bag instead of plastic bags.


Use a glass drinking bottle that can be washed out and used again. If you use items that can be reused, this results in less waste.

Become a Waste Picker

Start waste picking to make money. Waste pickers collect recyclable materials to resell to buyback centres.

Save water

Saving water is extremely important. All living species need water to survive. Always turn off your tap when you’re finished and fix all your plumbing leaks

Reduce power use

When you exit a room, always turn off the lights. Using electricity creates pollution. You will create far less pollution if you save electricity.

Did you see Science Spaza at Science Forum South Africa 2019?! 

Check us out!





We had an awesome time meeting and interacting with everyone who attended SFSA 2019! 

We look forward to seeing you again next year!

Climate change will affect South Africans in five sectors: health, bio-diversity, agriculture, water and cities. Though the spread of malaria isn’t expected to increase, cholera outbreaks will. As temperatures rise, farmers will need extra irrigation and maize, wheat and grape production particularly will be impacted. It is uncertain what the outcome of precipitation will be, but the east coast and central interior are likely to get more water, while the Northern and Western Cape are likely to get less. Coastal cities may be threatened by higher sea levels. For example, Durban’s sea-level could rise by 2.7 mm every year, making storm surges and coastal erosion worse. In general, as weather patterns become more extreme, fires, storms, flooding, and droughts are expected.


  • Many South Africans are living in poverty, have a high disease burden and inadequate housing. This means that they are not able to deal well with extra pressures like extreme climate events since they are already in a vulnerable state.
  • In some places, South Africa already has low and variable rainfall.
  • Most of South Africa’s surface water is already appointed to be used somewhere, so there isn’t much extra.
  • Agriculture and fisheries, which will be impacted, are important for food security and local livelihoods.

  • There is an increase in the average global temperature of about 1°C.
  • A 0.19 m rise in the average global sea level has been observed.
  • There is reduced snow cover in the northern hemisphere, melting ice sheets in Greenland and Antarctica and there’s a 4% decrease in Arctic ice.
  • Average precipitation over mid-latitude areas in the Northern hemisphere has significantly increased. There are more heavy rainfall events over most land areas. This leads to a higher risk of flooding in certain areas.
  • Since the 1970s, droughts are longer and more intense. Drying in the Sahel, the Mediterranean, southern Africa and parts of southern Asia.
  • Though some places have become colder, the general trend is a decrease in cold days and nights, with an increase in heat waves, as well as warmer days and nights.
  • Over 30% of the increase in carbon dioxide has been absorbed by the oceans. The oceans are now 26% more acidic and in combination with warmer seawater, this is impacting marine life.


Climate change has major impacts on biodiversity. Wildlife and plants will need to cope with:

  • Habitat destruction and extreme weather events.
  • Changed timing of seasonal events such as breeding and migration.
  • Important events could go out of sync – like flowering and pollination.
  • Species could become extinct or move to cooler locations.
  • Warmer, more acidic seawater kills sea creatures.
  • Some species, like  fish, are becoming smaller to cope with higher temperatures.


Unhealthy ecosystems cannot protect people against climate change. 

  • They cannot capture as much carbon and keep it out of the air.
  • They can’t protect against the impacts of extreme weather events.
  • If ecosystems aren’t doing their job, the air we breathe and water we drink can no longer be cleaned properly.
  • Excessive heat dries the soil, shortens growing periods and could increase weeds, pests and diseases. This could eventually result in complete crop failure.
  • Extreme weather events and unpredictable rainfall affects crops that humans eat.
  • Hotter conditions make it difficult to keep humans and livestock well-fed.
  • More disease puts those living with HIV/AIDS at risk. Other health concerns include hunger, malnutrition, air pollution and heat stress.
  • Many South Africans are living in poverty, have a high disease burden and inadequate housing. Because they are vulnerable, they can’t cope well with extreme climate events.


Very high temperatures are bad for the economy. A changing climate means a changing economy.

  • ENERGY: Hotter weather demands more electricity for air conditioning. Higher energy demand makes electricity prices climb.
  • FORESTRY: More disease outbreaks and resistance threaten forests and plantations. These are not just responsible for removing large amounts of carbon dioxide out of the air but could replace fossil fuels as a fuel source.
  • FOOD: Food prices are increasing. Income from  fisheries is declining due to smaller catches and destruction in coral reefs.
  • TOURISM: Tourism contributes to greenhouse gas emissions and has a massive carbon footprint.


Climate change burdens the poor. The disadvantaged are the most vulnerable to climate change. Reasons include:

1. More food and water insecurity

2. Higher food prices

3. Loss of jobs

4. Negative health effects

5. Being forced to move
