An increase in mass would cause more gravitational force between the Sun and the Earth and so the orbit would decrease in size.
However, birth rates do not account for a rise in mass, as all the materials which constitute us are from the Earth and its atmosphere anyway.

The Earth's mass can only be increased by meteorites that impact it, compared to the total mass of the Earth, this increase is very minor, it has an effect but too small to cause any significant change in the Earth's orbit.

More people dont mean more mass.
Every new human being is made of the same matter that is already available in nature. So they are not adding a single gram of matter to the planet.
Think about it; if you weight 150 pounds, you wern't born weighting 150, you gor 150 pound by eating food all those years, and your body transformed all that food in energy and body mass. So you are not adding more mass to the planet, you just took mass from nature an put it inside you.

Think recycling..! As more or less people and animals are born their mass comes from mass that's existed on Earth practically from when our planet first formed. For instance, if ten people are born with a combined mass of 1,000 kilograms that 1,000 kilograms is not *new* mass...it's simply recycled mass that's been around almost forever. Some of your own mass may have been part of the mass of a dinosaur that lived and died hundreds of millions of years ago.
The only true mass increase of our planet comes from infalling material, like meteorites, cometary dust, etc.,. In one year Earth gains around 400,000 tons of *new* mass.

People, plants, and animals are made of materials already found on Earth. You are made of the food you eat. The animals you eat are made of plants, and the plants you eat are made of air, water, and soil. The soil is made of pulverized rock and other plants. So everything you're made of is air, water, and rock: the constituents of the Earth.
It also wouldn't matter to the Earth's orbit what the Earth's mass was. The Earth's orbit is merely the Earth freely falling around the Sun, and as Galileo found when he dropped balls off the Leaning Tower of Pisa, everything falls at the same rate regardless of mass.

If,some way the mass of the earth increased it would have to increase orbital speed to maintain the same orbit,or it would spiral into the sun.

it looks like impossible. how can be mass of earth increased?
only way to this is something from out of atmosphere.

Yes, but it will take a lot of weight, maybe more than we can ever imagine to 'knock' the Earth out of it's alignment.
